Dynamic Titles with a multiple select filters

I am working with a visualization with many filters for:

Entity

Year

Patient Type

Product Line

I have not found a way to set up each of these as a multiple select property control type so that the title on my graphs/tables change as as filter changes and the data displays. It works fine as along as I don't use the multiple select property control type. 

For example: If I want to show both inpatient and outpatient types on my visualization, I get an error message on my visualization that says" No data to display. All data may have been filtered out or the data table is empty."

My property control Limit Data Using Expression is: [Inpatient Outpatient]="$map("sum([${InptOutptSelect}])",",")"

 

Any help would be much appreciated!

Thanks,

Helen
